What should be the normal blood pressure of an adult?

Correct option is A

Ans (a)
Sol. Explanation:
· A normal blood pressure for a healthy adult is typically considered to be 120/80 mmHg, where:
· 120 is the systolic pressure, which measures the pressure in the arteries when the heart beats.
· 80 is the diastolic pressure, which measures the pressure in the arteries when the heart is at rest between beats.
· Option (b), 130/90, indicates prehypertension or stage 1 hypertension, which requires attention.
· Option (c) and (d) represent values that are outside the range of normal blood pressure and are considered abnormal, with (d) being dangerously high.
